AI photo math solver with clear step-by-step solutions
Upload or paste a picture of a math problem and Mathful scans it, interprets the notation and produces a worked solution instead of just a raw number.
Every answer comes with the intermediate working, so you can follow the method and use the output as a study reference rather than a shortcut.
Handles arithmetic, word problems, pre-algebra and algebra, geometry, trigonometry, pre-calculus and calculus, statistics, matrix operations and more.
A dedicated calculator mode handles linear and quadratic equations, derivatives, integrals and matrix operations, showing the steps for each calculation.
AI sidebar and browser agent for reading, writing and research
A persistent panel that reads the page you are on and answers follow-ups with GPT, Claude or Gemini without copying content into another tab.
Summarise long articles, PDFs and YouTube videos, extract key points, and ask detailed questions about the source material.
Translate webpages, PDFs and images, compare bilingual output side by side, and have content read aloud for review on the move.
Delegate multi-step tasks across real websites — price comparison, form filling, research and inbox triage — using your existing logged-in sessions.
